Dormancy cycling in Polygonum aviculare seeds is accompanied by changes in ABA sensitivity
(Oxford University Press, 2020-07)
Polygonum aviculare seeds shows high levels of primary dormancy (PD). Low winter temperatures alleviate dormancy and high spring temperatures induce seeds into secondary dormancy (SD), naturally establishing stable seedbanks ...
Molecular mechanisms underlying the entrance in secondary dormancy of Arabidopsis seeds
(Wiley, 2016-01)
As seasons change, dormant seeds cycle through dormant states until the environmental conditions are favourable for seedling establishment. Dormancy cycle is widespread in the plant kingdom allowing the seeds to display ...
Cardiac hypertrophy and structural and metabolic remodeling related to seasonal dormancy in the first annual cycle in tegu lizards
(Elsevier B.V., 2013-07-01)
Morpho-functional adjustments in the heart of juvenile tegu lizards (Tupinambis merianae) were analyzed at distinct seasonal periods to investigate how the demands of growth and of energy saving are reconciled during the ...
Alterations in the pattern of peroxidase isoenzymes and transient increases in its activity and in H2O2 levels take place during the dormancy cycle of grapevine buds: The effect of hydrogen cyanamide
(2004)
Polymorphism of peroxidase (Px) and changes in its activity and in H 2O2 content were studied in buds of grapevine during dormancy. Three isoforms of Px were detected in bud-extracts, two basic and one acidic, however, the ...
Similarities between natural and chemically induced bud-endodormancy release in grapevine Vitis vinifera L.
(ELSEVIER SCIENCE BV, 2010-05-19)
Bud-break in grapevines (Vitis vinifera L) can be poor and uneven in locations that have warm winters
with insufficient chilling. Growers in these regions use hydrogen cyanamide (HC), a dormancy-breaking
compound, to ...
On the mechanism of dormancy release in grapevine buds: A comparative study between hydrogen cyanamide and sodium azide
(2009)
Sodium azide (NaN3), a well-known inhibitor of mitochondrial respiration, stimulated bud-dormancy release in grapevines similar to hydrogen cyanamide (HC), while HC, a well-known dormancy release agent, inhibited the O2 ...
A stratification thermal time-based model as a tool for designing efficient methodologies to overcome seed dormancy constraints to kiwifruit seedling production
(Elsevier Science, 2021-02)
Kiwifruit (Actinidia deliciosa A. Chev. C.F. Liang and A.R. Ferguson) seedling production in the nursery is usually impaired because of low seed germination resulting from primary dormancy. Dormancy of hydrated seeds is ...
Temperature and photoperiod effects on dormancy status and life cycle parameters in Aedes albopictus and Aedes aegypti from subtropical Argentina
(Wiley Blackwell Publishing, Inc, 2020-08)
Aedes albopictus (Diptera: Culicidae) distribution is bounded to a subtropical area in Argentina, while Aedes aegypti (Diptera: Culicidae) covers both temperate and subtropical regions. We assessed thermal and photoperiod ...
Spontaneous Gene Flow between Cultivated and Naturalized Vicia villosa Roth Populations Increases the Physical Dormancy Seed in a Semiarid Agroecosystem
(MDPI, 2021-05)
Hairy vetch (Vicia villosa Roth) is the second most cultivated vetch worldwide being used as a forage and cover crop. As it is not domesticated, it displays several wild traits including seed dormancy. The physical seed ...
Daily and annual cycles in thermoregulatory behaviour and cardio-respiratory physiology of black and white tegu lizards
(Springer, 2015-12-01)
This study was designed to determine the manner in which metabolism is suppressed during dormancy in black and white tegu lizards (Tupinambis merianae). To this end, heart rate (f (H)), respiration rate (f (R)), and deep ...
